Running PAWLS on MacOS M1 Machine

[sanjanachin]

Hi!

I'm trying to use PAWLS to collect PDF annotations, but the pawls command is not working when I try to follow the installation on MacOS. Specifically, after running:

$ pawls

I get the following response:

Traceback (most recent call last):

When I used the same installation procedure on a Ubuntu machine, everything worked normally, and I was able to use this process to add custom PDFs.

But, I am now unable to export any annotations because the pawls command is not working.

Any ideas?

Thanks!

@sanjanachin are you currently using an Apple Silicon Machine (e.g. M1 MacBook Pro)?

[sanjanachin]

@soldni Yes, I'm using an M1 Mac.

If you can, I would recommend managing your environment with conda, and installing pycrypto via `conda install pycrypto`.
